Pituitary Adenoma

Cyberknife Robotic Radio Surgery Treatment for Pituitary Adenoma

The pituitary gland is referred to as the master gland of the human body. It is because it controls almost all of the body’s endocrine functions by secreting nine particular hormones like prolactin, oxytocin, antidiuretic hormone [ADH], thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, and human growth hormone- all of which control activities of other endocrine glands. The pituitary gland is broken into two lobes: front or anterior and rear or posterior. Benign tumors commonly grow about the anterior part of the gland. Tumors rarely develop on the posterior part of it. The majority of brain tumors are pituitary tumors, making them the third most typical variety of brain tumor. Among the pituitary tumors, pituitary adenomas are the most common. These adenomas could additionally be identified depending on type of hormones they secrete. Hormonal imbalance is a very common clinical indication of the condition. The etiology of pituitary adenoma is unknown. Studies show that it results from DNA alterations that lead to rapid, unchecked growth, large enough to compress adjacent cells and structures. In rare events, these tumors bring about spontaneous hemorrhage or can lead to infarction. Optic chiasm, which is commonly discovered above the pituitary gland, is commonly effected resulting in double vision and eventually to progressive decrease in vision. Additional indicators linked to tumor’s location are chronic headache, reduction in peripheral eyesight, ptosis, seizures, facial numbness, hyperphagia or excessive eating and hypophagia or unusual eating of small amount of food. Other symptoms associated with the hormone it emits are: hyperhydrosis or excessive sweating, appetite decline, diminished sexual interest, queasiness, issues concerning menstrual periods, bowel irregularity and polyuria or excessive urination, growth delay, pubertal delays and galactorrhea or milk secretion without pregnancy. Surgery, radiotherapy, stereostatic radiosurgery and cyberknife are possible treatments for pituitary adenomas.
Treatments for pituitary adenomas depend on its location, the type of hormone released and its degree of metastasis. Each treatment aims to normalize hormonal levels and to eliminate or reduce the tumor’s size. In a surgical procedure, elimination of the tumor is accomplished through craniotomy. Having said that, when the pituitary gland is taken away or impaired, life-long hormonal replacement therapy is necessary. Prevalent clinical risks brought about by the operation is meningitis, which is resulting from leakage of cerebrospinal fluid through the nose triggering the inflammation of brain and spinal column membranes. In contrast, radiotherapy may be undertaken as adjunctive therapy to the surgical removal of the tumor. Stereotactic radiosurgery makes use of extremely accurate radiation beams to shrink the tumor. This is usually performed on individuals whose tumors will not respond to surgery or medications. Among the stereostatic radiosurgeries, cyberknife is the most common and successful.
Cyberknife Radiosurgery for pituitary adenoma offers the benefits of both conventional radiation and radiosurgery treatment. The procedure reduces the radiation danger to susceptible structures bordering the tumor including optic chiasm and hypothalamus. Among the treatments, cyberknife is pain-free. No anchoring screws, scalpels and support frames are used. It utilizes high doses of radiation to correctly concentrate on the tumor, lessening injury and destruction to nearby tissues. Risk of hemorrhage or blood loss is also averted. This process may be accomplished on an out-patient basis. Therefore, the patient can return to his usual lifestyle following the procedure; no recovery time is required. Noted for this effective kind of procedure is the Colorado CyberKnife. They prefer the latest equipment and software to help more individuals in effectively managing their tumors, in less time while diminishing the risk for complications. Because of this, they are well-known in the field of oncology.
